NAME

       lunzip - decompressor for the lzip format

SYNOPSIS

       lunzip [options] [files]

DESCRIPTION

       Lunzip  is a decompressor for the lzip format. It is written in C and its small size makes it well suited
       for embedded devices or software installers that need to decompress  files  but  don't  need  compression
       capabilities. Lunzip is fully compatible with lzip-1.4 or newer.

       Lunzip  provides  a  'low  memory'  mode  able  to  decompress  any file using as little memory as 50 kB,
       irrespective of the dictionary size used to compress the file. To activate it, specify the  size  of  the
       output buffer with the '--buffer-size' option and lunzip will use the decompressed file as dictionary for
       distances beyond the buffer size. Of course, the  smaller  the  buffer  size  used  in  relation  to  the
       dictionary  size,  the  more  accesses to disk are needed and the slower the decompression is.  This 'low
       memory' mode only works when decompressing to a regular file and is intended for systems  without  enough
       memory (RAM + swap) to keep the whole dictionary at once.

OPTIONS

       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -a, --trailing-error
              exit with error status if trailing data

       -c, --stdout
              write to standard output, keep input files

       -d, --decompress
              decompress (this is the default)

       -f, --force
              overwrite existing output files

       -k, --keep
              keep (don't delete) input files

       -l, --list
              print (un)compressed file sizes

       -o, --output=<file>
              if reading standard input, write to <file>

       -q, --quiet
              suppress all messages

       -t, --test
              test compressed file integrity

       -u, --buffer-size=<bytes>
              set output buffer size in bytes

       -v, --verbose
              be verbose (a 2nd -v gives more)

       --loose-trailing
              allow trailing data seeming corrupt header

       If  no  file  names  are  given, or if a file is '-', lunzip decompresses from standard input to standard
       output.  Numbers may be followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024, M = 10^6,
       Mi  =  2^20, G = 10^9, Gi = 2^30, etc...  Buffer sizes 12 to 29 are interpreted as powers of two, meaning
       2^12 to 2^29 bytes.

       Exit status: 0 for a normal exit, 1 for environmental  problems  (file  not  found,  invalid  flags,  I/O
       errors,  etc),  2  to  indicate a corrupt or invalid input file, 3 for an internal consistency error (eg,
       bug) which caused lunzip to panic.
